AWNING.

SPECIFICATION forming part of Letters Patent No. 744,845, dated November 24, 1903. Application filed May 22, 1903. Serial No. 158,335. (No model.)

ings; and I do hereby declare the following i to be a full, clear, and exact description of the invention, such as will enable others skilled in the art 1-0 which it appertains to make and use the same.

My invention relates to an improvement in awnings, the object being to provide an awning designed more especially for use on buildings with low fronts, Where it is desirable to have a large extent of awning and where the height of the building will not permit of the use of an ordinary rod, and also for general use where it is desired to have a large extent of awning.

A further object is to provide an awning which will be automatic to the extent that it will open itself when the awning is released.

With these objects in view my invention consists in certain novel features of construction and combinations of parts, which will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view showing the awning lowered. Fi 2 shows it raised. Fig. 3 is a detailed view, and Fig. 4 is a modification.

A represents a guide or slide rod. There are at least two of these, as shown, secured vertically to the side of the building to which the awning is to be attached, one at either end ofthe space to be covered by the awning, and if more than two arms are deemed necessary to give proper support and solidity to the awning when lowered then there will be as many additional guide or slide rods as additional arms.

The awning-frame consists of a lazy-tongs construction pivoted to the stationary bracket or hinge 1, secured to the wall or other support at the lower end, and the other member of the tongs comprises parallel rods B, connected at their ends behind guide-rod A, and a suitable roller 0 may be mounted between the rods to run against the rear face of guiderod A, and thus reduce friction.

The several bars of the lazy-tongs are pivotally connected together in the usual manner. The end, however, may project a short distance beyond the pivotal points, as 3 3, in order to provide additional bearing.

The outer bar or arm 5 of the lazy-tongs is extended outward any desired distance. The length may of course be varied, but preferably this bar or arm extends approximately from the lower end of the lazy-tongs when folded up, as shown in Fig. 2, to the roll around which the awning runs, or in case no roll is used then to such a height that the awning-pole will be brought nearly in contact with the place on the building to which the upper part of the awning is fastened. The outer bar or arm 5 may also from its con nection with the other bar of the lazy-tongs be curved outward, so that the awning-pole will be thrown in the same horizontal plane with the brackets on the building, or even lower when the awning is lowered.

Instead of constructing the member B as above explained I might construct the same as shown in Fig. 4. In this form of my invention B is a single rod extending between parallel guide-rods A and made with lateral projections E to extend behind the guiderodsA and hold the member Bin place. Suitable rollers D may be located on these projections E to run against the rods to reduce friction.

lVith my improvements, which are designed as an improvement on the construction disclosed in my Patent No. 593,147, granted to me November 2, 1897, there is no possibility of the member B sticking to guide-rods A due to the accumulation of rust or other causes.

The lazy-tongs are in general disposed horiawning farther and a shorter length of bar or i a less number of bars when not so far.

Several advantages are possessed by the present construction over others disclosed by the prior state of the art. Heretofore it has been necessary to have the lazy-tongs obliquely disposed. In the present invention such disposition may be either oblique or horizontal.

The present invention has all the advantages of the oblique lazy-tongs-that is, it has the benefit of the force of gravity in assisting to lower and spread the awning. It also has the added advantage of extending out horizontally, so that side curtains can be used to advantage, whereas with the oblique construction and a roller side curtains can not be used. Again, no mechanism of lever or other construction is required to lower the awning. When the awning is released, it drops to any position desired, and the long outer arm or bar assists in lowering the awning. Moreover, it will be observed that the sliding part is above, whereas heretoforeit has been below, the advantage being that the present construction is very compact, less liable to get out of order, and absolutely automatic. In addition, should the sliding part be below, as heretofore, the tendency of the lazy-tongs will be to close up, thus throwing the awning against the building, which defect has heretofore been overcome by the lever mechanism above spoken of or by placing the lazy-tongs in an oblique position, both of which objections the present construction overcomes.

I might bend the slide -rods A to various curvatures to facilitate the movement of the awning, and various other slight changes guide-rod, of lazy-tongs, one member having a pivotal support below the guide-rod, and a roller projecting laterally from the rear end of the other member and disposed behind the guide-rod.

2. In an awning, the combination with a guide-rod, of lazy-tongs, the lower member thereof having a stationary pivot, and the upper member comprising parallel rods connected behind the guide-rod.

3. In an awning, the combination with a guide-rod, of lazy-tongs, the lower member thereof having astationary pivot, and the upper member comprising parallel rods connected behind the guide-rod and a roller between said rods to run against the inner face of the guide-rod.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
